Kiyosu, Japan, October 9, 2019: Toyoda Gosei Co., Ltd. will exhibit its vertical GaN power device at CEATEC 2019, an IT and electronics technology fair held at Makuhari Messe in Chiba, Japan from October 15 through October 18, 2019.

Power devices are electronic components that convert electricity. They are widely used in power converters (inverters and converters) in home appliances, automobiles, industrial machines, and more. Toyoda Gosei has worked with gallium nitride (GaN) for many years as a main material in blue LEDs, and has been developing a GaN power device that takes advantege of the superior properties of GaN as a power device material, such as its high breakdown voltage. The GaN power device developed by Toyoda Gosei will help to make power converters more highly efficient and compact.

At CEATEC, the company will present the examples of a compact power inversion circuit using vertical GaN power devices.
